According to the periodic table ,( )still some elements undicovered.
A.there seem to be B.it seems to be
C.it seems that D.here seem
答案是什么,为什么?

选 A there seem to be”有什么东西“,一般用 there + be.选项BCD都没有

选A
其实there be结构里都可以理解为一个倒装,some elements undiscovered seem to be there.这样你就可以理解啦。

A正确。
THERE SEEMS TO BE……似乎还有……。表示一种揣测。
根据这周期表,似乎还有某些元素没有被发现。
